Everything you need to know about choosing PP Hollow Construction Formwork
PP hollow formwork also called Plastic Construction Formwork is made of modified PP powder with other additives by heating and extruding. It has high reuse times and water proof can replace traditional plywood. Eco friendly and easy to assemble. It is a style of building concrete structures with reusable plastic molds. This method requires almost no labor skills, gets the job done in record time, with minimal wastage in the process.
PP hollow construction formwork is resistant to water and heat, which makes it strong and light compared to wood or metal. We can meet the thickness or strength of you for your specific situation. PP hollow formwork is specially processed on surface. This kind of formwork has a stronger & smooth surface, it can be easily released and it can bear higher temperatures like above 45°C for the recycling process. PP Hollow Construction Formwork can be kept stable and smooth in hot weather and seasons. It has no absorption of moisture, no deformation, no mildew. So, you can easily count on them to use in different environments and underground.

Basic Installation Requirements of PP Hollow Construction Formwork
■ The joints of the formwork should be tight and flat without misalignment.
■ The joints of the formwork should be on the wood/steel frame. If there are gaps, tape should be used to seal them.
■ The hole direction of the hollow plastic formwork should be perpendicular to the horizontal plane, and the hole should be sealed with adhesive tape to prevent the cement slurry from seeping into the hole.
■ The connection between the hollow plastic formwork and the wood/steel frame should be firm, and no relative displacement should occur during construction.
